What are the best resource to study the following: JavaScript, AJAX, CodeIgniter Smarty?
OReilly's Javascript: The Definitive Guide, 5th Edition (or later) http://www.amazon.com/JavaScript-Definitive-Guide-David-Flanagan/dp/0596101996/ref=dp_ob_title_bk
Though perhaps not suited as a first book on JavaScript, I recommend
JavaScript - the Good Parts by Douglas Crockford. It will keep you from doing some dumb things.
CodeIgniter has a great User Guide. Just download CI and start building a simple web site, using the guide as a starting point and reference.
Also, I would recommend using jQuery for your JavaScript and AJAX - it will make your life much easier!
Digging into JQuery and using it is a great way to crash course into something more complex than "hello world" with javascript
In general, you will learn a lot if you just do stuff in this fashion.
- Pick a feature you think is cool
- Google it to find a solution
- Instead of copy/paste, make sure you understand what the code actually does, and how
- Change it in some way to make sure your understanding is correct \
- Use Google to find out why your changes failed
- Rinse/Repeat
